Blondies with Chocolate Chips and Walnuts

This unbeatable blondie recipe combines the buttery flavor and chocolate chips from everyone's favorite cookies with the appealing texture of the best brownies. For the neatest pieces, cool the blondie cake completely before slicing. Then, using a serrated knife, cut with a sawing motion.

Preheat oven to 350 degrees. Brush an 8-inch square baking pan with butter; line pan with a piece of parchment paper, leaving a 2-inch overhang on two sides. Butter paper.

In a large bowl, whisk butter and sugars until smooth. Whisk in egg and vanilla. Add flour and salt; mix just until moistened (do not overmix). Fold in 1/2 cup each chocolate chips and walnuts. Transfer batter to prepared pan; smooth top. Sprinkle with remaining chocolate chips and walnuts.

Bake until top is golden brown and a toothpick inserted into the center comes out clean, 40 to 45 minutes. Set pan on a wire rack, and let cool completely. Using parchment overhang, lift cake from pan and transfer to a cutting board; cut into 16 squares. Store blondies in an airtight container at room temperature, up to 2 days.
